Michael Vick has appeared in a new PSA for the Humane Society asking people who may hear or know of dogfighting rings to report them. Wayne Pacell, head of the Humane Society and one of Vick's biggest advocates since his release from prison says he's been an important ambassador for the anti-dogfighting cause.

"Michael Vick served time for illegal dogfighting, and he’s an important ambassador for the message that dogfighting is cruel, that it’s a felony, and that we must be good to animals," said Pacelle. "Mike has been making appearances for HSUS’ anti-dogfighting campaign, and these videos will broaden our audience and remind people to report animal fighting crimes and help to build humane communities."
